Tested on android but I am not sure about all iphones due to webgl support but new ones should support it. I tried iphone 4s on http://www.browserstack.com/ it works. You can try all device on browserstack,too.

They are not same if you are talking about http://cssdeck.com/labs/colorpong this game. If you look closer you can see that pong and color logic are same but my game created with construct 2 also screen size and some mechanics are different, too.
